1 Claim.

This invention relates to improvements in devices to clean radiator cores of vehicles.

An object of this invention is to clean the tubes and the separators of a radiator core by means of an improved nozzle which is adapted specifically for the purpose of introducing a fluid, as air or water, under pressure, on the external surfaces of the separators and tubes thereby cleaning the core, said nozzle consisting of a coupling which is adapted to connect with a conduit attached to a suitable source of fiuid under pressure, and a tube or conduit attached to the coupling with a specially provided discharge end including a fiat upper wall with an orifice therein so that the fluid under pressure is emitted in a stream whose axis is perpendicular to the longitudinal axis of said tube or conduit.

Other objects such as the capability of effectively cleaning a radiator core without the removal thereof, will become apparent in following the description of the illustrated forms of the invention.

In the drawings:

Figure 1 is a top view of one form of the device;

Figure 2 is a side view of the device in Figure 1;

Figure 3 is a longitudinal sectional View of the device in Figure 1;

Figure 4 is a transverse view taken substantially on the line ll-4 of Figure 2 and in the direc tion of the arrows showing the nozzle tip con-- struction;

Figure 5 is a transverse view taken substantial- 1y on the line 5--5 of Figure 2 and in the direction of the arrows; and,

Figure 6 is a modified term of the device, the differentiating feature being the use of a tube of slightly larger diameter than that in Figure 3.

In carrying out the invention I have provided a. coupling which consists of an internally threaded collar ll! adapted to connect with the male coupling collar [4 at one end of a typical hose or conduit 12. The hose or conduit is adapted to attach at its upper end with a suitable source of fluid under pressure, as air or water.

A gasket I6 is disposed in the collar Ill to serve the usual sealing purpose. A flange I8 projects from the collar I and forms a seat for the tube or conduit 2!]. The tube or conduit in the embodiment of Figure 3 is disposed within the flange l8 and held in place by any suitable means, as a friction fit, soldering or other expedient. The embodiment of Figure 6 employs a larger diameter tube or conduit 22 which is disposed on the outside surface of the flange l8 and. which is similarly held in place.

At the outer or discharge end of the tube there an upper flat wall formed as a part of the conduit with a discharge opening or orifice 25 therein intermediate the ends of said flat wall 263. A pair of vertical depending walls and 32 extend from the side edges of the fiat wall 26 and an angularly inclined end wall 36 is fixed alon the lower edges of said depending walls 3|] and. 32. The extreme outer end of the wall 36 is bent slightly as at 38 to fit flush against the lower surface of the flat wall 25 whereby it may be soldered or otherwise rigidly fixed thereto. This forms a substantially closed discharge extreme outer end for the tube or conduit 20 so that the fluid under pressure must pass through the orifice 26 to direct the fiuid properly between and around the tubes and separators of a conventional radiator core.

In operation, the described nozzle is inserted at Various places between, around and adjacent the core of the radiator so that the insects, dirt and other foreign matter is blown and melted therefrom. By employing the nozzle as described, it may be inserted in small and otherwise diificult to reach places.

Having thus described the invention, what is claimed as new is:

A device for cleaning the core of a radiator without removing the radiator from the vehicle, said device comprising a tube having a. coupling at one end to attach to a conduit conducting fluid under pressure, said tube having a nozzle at the extreme opposite end, said nozzle being closed at its outer end and provided with a fiat upper wall located in a plane parallel to the longitudinal axis of said tube and also provided with a lower wall converging toward the extreme outer end of said fiat upper wall, and an orifice formed in said flat upper wall adjacent to the outer end of said fiat upper wall to discharge the fluid therefrom, and said orifice having a discharge axis perpendicular to the longitudinal axis of said tube whereby the fiuid is emitted at substantially right angles to the tube. 7
